Resumo: Beans, cassava and corn are rainfed crops grown in the semiarid of the 184 Ceará State municipalities. Pentecoste and Sobral are municipalities located in the semi-arid areas susceptible to desertification in Ceará. Temporal and spatial instability of rainfall is characteristic of the semiarid. The research compares rainfall in Ceará and these municipalities between the years 1974 and 2018. It makes tests in order to observe whether the State and municipal rainfall can be classified in a pattern defined in the survey. Statistical tests are also developed to assess whether rainfalls interact with yields and production value per hectare of crops in the period studied in Ceará, Pentecoste and Sobral. Productivities and production values ​​per hectare of beans, cassava and corn are aggregated using the factor analysis method. The data are from FUNCEME and IBGE. The results show that the state and municipal rainfall can be classified according to the tested standard. It is also observed that in Pentecoste and Sobral there was a higher incidence of years with drought than in Ceará. The general conclusion of the research is that there are synergies between the instabilities of rainfall and the productivity of rainfed crops in Ceará, Pentecoste and Sobral between 1974 and 2018.

Pentecoste y Sobral son municipios ubicados en las zonas semiáridas susceptibles de desertificación. La inestabilidad temporal y espacial de la lluvia es característica de los semiáridos. La investigación compara las precipitaciones en Ceará y estos municipios entre los años 1974 y 2018. Evalúa si las precipitaciones estatales y municipales se pueden clasificar en un patrón definido en la encuesta. Las pruebas estadísticas se desarrollan para evaluar si las precipitaciones interactúan con los rendimientos y el valor de producción por hectárea de cultivos en el período estudiado en Ceará, Pentecoste y Sobral. Las productividades y los valores de producción por hectárea de frijoles, yuca y maíz se agregan utilizando el método de análisis factorial. Los datos son de FUNCEME e IBGE. Los resultados muestran que las precipitaciones estatales y municipales se pueden clasificar de acuerdo con el estándar probado. También se observa que en Pentecoste y Sobral hubo una mayor incidencia de años con sequía que en Ceará. La conclusión general de la investigación es que existen sinergias entre las inestabilidades de la lluvia y la productividad de los cultivos de secano en Ceará, Pentecoste y Sobral entre 1974 y 2018.Feijão, mandioca e milho são lavouras de sequeiro cultivadas no semiárido em todos os 184 municípios do Ceará. Pentecoste e Sobral são municípios cearenses situados nas áreas semiáridas susceptíveis à desertificação, sendo a instabilidade temporal e espacial das chuvas uma característica do semiárido. A pesquisa compara as precipitações de chuvas no Ceará e nesses municípios entre os anos de 1974 e 2018. Avalia se as pluviometrias do estado e dos municípios podem ser classificadas em padrão definido na pesquisa. Elaboram-se testes estatísticos para avaliar se as pluviometrias interagem com as produtividades e valor da produção por hectare das lavouras no período estudado no Ceará, em Pentecoste e Sobral. As produtividades e valores da produção por hectare de feijão, mandioca e milho são agregadas usando método de análise fatorial. Os dados são da FUNCEME e IBGE. Os resultados mostram que as pluviometrias do estado e dos municípios podem ser classificadas de acordo com o padrão testado. Observa-se também que em Pentecoste e Sobral houve maior incidência de anos com estiagem do que no Ceará. A conclusão geral da pesquisa é que há sinergias entre as instabilidades das pluviometrias com as produtividades das lavouras de sequeiro no Ceará, Pentecoste e Sobral entre 1974 e 2018.Editora Unimontes2020-11-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigoapplication/pdfhttps://www.periodicos.unimontes.br/index.php/cerrados/article/view/233310.46551/rc24482692202022Revista Cerrados; v. 18 n. 02 (2020): Revista Cerrados ; 371-3942448-26921678-8346reponame:Revista Cerrados (Montes Claros.
